INCANDESCENT-GAS-MANTLE BOX.

Applicationfiled October 25, 1919. Serial No. 333,218.

To all whomz'tmay concern:

Be it known that I, JosnrH HANnroRn BARNES, a subject of the King of Great Britain, residing at 1 lVinif'rid road, Stockport, in the county of Chester, England,

. have invented certain useful Improvements in Incandescent-Gas-Mantle Boxes, as set forth in the annexed specification.

This invention relates to incandescent gas mantle boxes of the kind formed from a single cardboard blank cut and scored in such a manner that it can be folded to form a complete box with lid.

The object of the said invention is to enable boxes of this kind to be secured with ease in the folded position and to facilitate the insertion and inspection of the mantle therein.

According to my invention the box is made from a cardboard blank havinga rectangular piece cut out at one corner and in addition to a portion forming a lid is provided at one part with a substantially central aperture, said part forming the top of the box proper and being situated be neath said lid and said aperture and cut corner rendering the interior of the box readily accessible for inserting and inspecting the incandescent gas mantle.

For the purpose of holding the parts of the box in correct position, a tab formed on the blank is tucked between two parts of the blank constituting one side of the box and a wire stitch is employed to secure said tab and adjacent parts together, a wire stitch being also employed to secure together the parts forming the opposite side of the box. Said aperture facilitates handling and observation during the insertion of the wire stitches.

The blank is preferably cut and scored and the aperture punched therein at one operation.

I attain this object by the means illustrated in the accompanying sheet of drawings, in which- Figure 1, is a front view of the cardboard blank ready to be folded.

Fig. 2 illustrates the first stage in the folding of the blank while- Fig. 3 illustrates the second stage.

Fig. 4 is a side view illustrating the final stage in folding the blank to form the box.

Referring to Fig. 1, the cardboard blank has two longitudinal cuts 1 and 2 and a number of longitudinal and lateral sc'orings indicated in the drawing by the broken lines, these scorings being on the underside of the blank. These cuts and scorings are not new, neither is the gap 3 which is provided on the part b constituting the platform for the mantle. I however cut out a rectangular piece from the blank to form the broken corner 4i and 1 form an aperture 5 in the part c of the blank. I also shape the part Z of the blank so that it can be readily slipped into position when the blank is folded to form a box.

To form a box the blank is folded in the known manner by first folding the part Z) and c and then the part a; so that they assume the position shown in Fig. 2. It will be observed however that at this stage no top is formed on the box. The next operation of folding is also known, the part at being first folded at right angles to the part A. and the parts 6, f and g being then folded around the parts 6 and a. At this stage the top of the box is formed of the part 9 having the aperture 5 and the fingers of the operator can be inserted for the purpose of adjusting the sides a and 0 so as to bring the platform Z) into its correct position. The part it is then tucked between the parts 0 and d as shown in Fig. 3 and while the parts are retained in position by the operator, with the aid of the aperture 5, wire stitches 6 and 7 are inserted through the parts d, h, 0 and a, f respectively.

The mantle can now be inserted in the usual way the aperture 5 however enabling the person inserting the mantle to see that the legs provided on the mantle holderare inserted beneath the platform and that the mantle proper does. not contact with the sides or back of the box.

Fig. 4: shows the box in a position at right angles to that shown in Figs. 2 and 3, the position of the parts i, j and is before the further folding takes place being shown in long and short dotted lines. These parts are folded into the position shown in full lines, and the part Z is tucked between the parts A and g in the known manner to close the box.

I claim:

A cardboard blank comprising in combination a broken corner at one end of the blank; two longitudinal cuts in said blank extending from said end of the blank to Within a short distance of the opposite end ed to cover the front of the box and said thereof and dividing the blank into three aperture when the blank is folded. parts connected together at said opposite Signed at Manchester, in the county of end; a gap formed in one side of the blank; Lancaster, England, this 9th day of Octo- 5 an iperture formed through one corner 05 her, 1919.
